The mechanism by which gauge and gravitational anomalies cancel in certain string theories is reviewed. The presentation is aimed at theorists who do not necessarily specialize in string theory. Talk presented at 2001: A Spacetime Odyssey – the inaugural conference of the Michigan Center for Theoretical Physics
After years of efforts to push the LEP performance to, and indeed beyond, the limits of what had been believed possible, hints of a signal of a Higgs boson at 115GeV/c appeared in June 2000, were confirmed in September, and confirmed again in November. Spending an additional six-month period with LEP would have given the unambiguous opportunity of a fundamental discovery. Instead, this possibil...
machines that can interact with them as they interact with each other. Science fiction writers have given us these goals in the form of HAL in 2001: A Space Odyssey and Commander Data in Star Trek: The Next Generation. However, at present, our computers are deaf, dumb, and blind, almost unaware of the environment they are in and of the user who interacts with them. In this article, I present th...
The pH on the frustule of individual cells of the marine centric diatoms Coscinodiscus granii and Coscinodiscus wailesii (Bacillariophyceae) was measured with pH microsensors in culture media with increasing pH values of 8.04, 8.14, and 8.22, respectively. In 85-96% of the C.granii cells the pH on the frustule was up to 0.4 units higher than that of the medium, reaching a maximum pH 8.95. Only ...
Why do computers need emotional intelligence? Science fiction often portrays emotional computers as dangerous and frightening, and as a serious threat to human life. One of the most famous examples is HAL, the supercomputer onboard the spaceship Discovery, in the movie 2001: A Space Odyssey. HAL could express, recognize and respond to human emotion, and generally had strong emotional skills – t...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
Vagueness is not undecidability, but undecidability does enter into an explanation of why there is vagueness. My theory, called the Undecidability Theory of Vagueness, explains vagueness largely as a result of the fact that we are computationally bound.1 Vagueness is not due to any particularly human weakness, but due to a weakness that any computationally bound agent possesses; even HAL from 2...
When measured over decades in countries that have been relatively stable, returns from stocks have been substantially better than returns from bonds. This is often attributed to investors’ risk aversion: stocks are thought to be riskier than bonds, and so investors will pay less for an expected return from stocks than for the same expected return from bonds. The game-theoretic probability-free ...
A new species of Habralictus Moure (Apoidea, Halictidae) is described from the island of Dominica, Habralictus gonzalezisp. n. The species is distinguished from other West Indian Habralictus and a key is provided to the West Indian Habralictus. Brief comments on the genus Habralictus and bee species of Dominica are provided.
